TECHNICAL FIELD

Exemplary embodiments of the present invention relate generally to an exercise rope handle.

BACKGROUND

Jumping over a rope (or jump rope) is a form of exercise that is well known. Jump rope, as the activity (and rope itself) is often referred to in the United States, likely originated hundreds of years ago. Originally, the rope may have been a simple length of rope repurposed from its original use and converted to a toy. Over time, handles were added to the rope and the rope may have been weighted to improve the characteristics of its swinging action. In addition to a form of entertainment, jump rope has taken a more serious turn and become popular as a form of exercise. In particular, jump rope has become a facet of exercise programs that combine various exercises which function together to vary the area of the body exercised and the type of exercise performed (i.e. strength, agility, and cardiovascular improvement). Such a combination of exercise is referred to as cross training. An organized form of cross training that has become extremely popular is known as CrossFit (CrossFit, Inc. Washington D.C.). Because of this increase in popularity and the desire for those engaged in such engaged in such exercise programs to have high quality exercise equipment, there is a need for a high performance, durable and easily maintained jump rope system.

DETAILED DESCRIPTION OF EXEMPLARY EMBODIMENT(S)

Various embodiments of the present invention will now be described in detail with reference to the accompanying drawings. In the following description, specific details such as detailed configuration and components are merely provided to assist the overall understanding of these embodiments of the present invention. Therefore, it should be apparent to those skilled in the art that various changes and modifications of the embodiments described herein can be made without departing from the scope and spirit of the present invention. In addition, descriptions of well-known functions and constructions are omitted for clarity and conciseness.

As is illustrated in FIGS. 1a and 1 b, an embodiment of the invention may comprise a grip section 102 to which at least one clamp 104 may be affixed. As is illustrated in FIG. 1 b, embodiments of the invention may be equipped with a single clamp 104, leaving the opposite end of the grip without a claim. As is illustrated in FIG. 1 c, clamps may be removably secured by hardware such as, but not limited to screws 106.

FIGS. 2a-2e illustrate an embodiment of the invention in various stages of assembly. As is shown in FIG. 2a , an embodiment of the invention may comprise a grip section 102, at least one clamp 104, an end cap 202, and a bearing assembly (shown assembled in FIG. 2c as 204). As is illustrated in FIG. 2a , the bearing assembly 204 may be comprised of at least one bearing 206, a shaft 208, a spacer subassembly 210, and an attachment device 212. As is illustrated, the embodiment shows an attachment device 212 formed using a split ring. In the illustrated embodiment, the attachment device serves two functions; the first is to secure the shaft 208 and spacer 210 to the bearing 206. As is illustrated in the embodiment, the shaft may comprise a hole formed in the shaft 214. Also, the shaft may comprise a means for preventing it from passing completely through the bearing 216. The illustrated means is a collar shape 216 but may be, without limitation, an enlarged portion of the shaft, a fastener, or a second hole and split ring. The second function of the attachment device 212 may be to attach a rope as illustrated in FIGS. 3a and 3b at 302. Referring again to FIG. 2a , the bearing 206 of the bearing assembly 204 may be formed from a sealed or semi-sealed bearing assembly. Examples, without limitation, of such bearings 206 may include ball bearings, roller bearings, or bearings employing plastic materials such as ultra high molecular weight (UHMW) polyethylene bearing surfaces. Roller or ball bearings may be formed using metal or ceramic materials. In addition, in embodiments of the invention, bearing assemblies 204 may comprise more than one bearing 206. In such an embodiment, a plurality of bearings may be positioned on the shaft 214. To accommodate these bearings, the shaft 214 may be extended, the spacer 210 may be reduced in length, or a combination of the two may be used.

As is illustrated in FIG. 2b , the shaft 214 may be placed in an opening formed in the center of the bearing 206 and a spacer 210 placed upon the shaft. As is illustrated in FIG. 2c , an attachment device 212 may then be placed through a hole formed in the shaft 214. As is illustrated in FIG. 2e , the bearing assembly 204 may be positioned in an end of the grip section 102. As is shown, a clamp 104 may be positioned on the grip section 102 and secured using a screw 106.

Other methods of securing the clamp may be used. One such method is illustrated in FIGS. 4a and 4b . In such an embodiment, a clamp 105 may be configured such that it is compressively affixed to the grip section 102. As illustrated, such a clamp 105 may be formed in a manner that does not embody a screw to affix the clamp to the grip section 102. As is illustrated in FIG. 5, once a bearing assembly 502 is inserted into the grip section 102, the clamp 105 may be compressed from its outer surface (crimped) such that it is caused to become affixed to the grip section 102, causing the grip section to be pressed tightly against the outer surface of the bearing assembly 502, securing the bearing assembly to the grip section 102.

Referring again to FIG. 4a , in another embodiment of the invention, the bearing assembly 502 may comprise a bearing 206, a shaft 402 that is at least partially threaded, a spacer 404, and an attachment device 406. As illustrated in FIG. 4b , the various components of the bearing assembly are assembled and the attachment device 406 positioned on the shaft 402. In the illustrated embodiment, the attachment device 406 threads onto the threaded portion of the shaft. In certain embodiments, the spacer 404 may be formed of a compressible material such that when assembled, the spacer exerts pressure against the attachment device 406, preventing the attachment device from becoming unthreaded from the shaft 402. Referring to FIG. 4c , in such an embodiment, the shaft may compressibly contact an inner race portion 408 of the bearing 206, facilitating the free movement of the shaft with regard to the outer race portion 410 of the bearing. This arrangement permits the shaft/spacer/attachment device to rotate independently of the outer race 410 and thus the grip section 102 of the handle. FIG. 6a illustrates a completed handle assembly 600 according to an embodiment of the invention. As is shown, the grip section 102 is secured to the bearing assembly 502 by a clamp 105. In the embodiment illustrated, the clamp 105 has been compressed in order to affix the bearing assembly to the grip section 102 such that when in use, the bearing remains securely within the grip section.

As is illustrated in FIG. 6b , a rope 302 may be inserted into openings 604 in the attachment device 406. In such a configuration, friction between the rope 302 and the attachment device 406 may be sufficient to hold the rope in place while the handle and rope is used to perform a jump rope exercise. In such an embodiment, the length of the rope may be easily adjusted to accommodate the physical characteristics of a user. For instance, a user who is shorter in stature may wish a rope that is shorter in length than would a taller person. In such a circumstance, the user may adjust the position of the rope by moving it through the openings in the attachment device.

In a similar embodiment, an attachment device 504 may be configured to accept a split ring 506 as illustrated in FIG. 5. In such an embodiment, the split ring may be used to attach the rope in a manner similar to FIG. 3a . In such an embodiment, the attachment device may have a single hole 508 as in FIG. 5, or may have multiple holes 604 as illustrated in FIG. 6 a.

As illustrated in FIGS. 5 and 6 b, the rope 302 may be attached to an attachment device 504 such that the attachment point is offset from the central axis of the shaft 402. As a result, the user of the jump rope handle may be exposed to a lesser amount of rope feedback through a handle in the user's hands.

In certain embodiments of the invention, a means may be provided to secure the jump rope handles when the jump rope is not being used. Such a means will allow a user to quickly and easily store the jump rope when the user is performing other exercise activities. An example of such storage is illustrated in FIG. 7. As is shown, the handle 702 is suspended from a ferrous surface 704 using a magnet found in an end portion 706 of the handle. Referring again to FIG. 2a , a high strength magnet 218 may be provided as part of the end portion 202 of a handle assembly. As is illustrated in FIG. 2c , a means 220 such as an adhesive tape or glue may be provided to secure the magnet 218 to the end portion 202. As is shown in FIG. 2d at 222, the magnet may be secured to the end portion 202 using an adhesive tape material 220. Once secure, the end portion may be attached to the grip section 102 as is illustrated at 224 in FIG. 2e . In other embodiments of the invention, such a magnet 218 may be molded into an end portion 706 or as illustrated in FIG. 8, may be molded into a grip section 102 of the handle 702. Alternatively, the magnet 218 may be affixed within the grip section 102 using a resin material. Other embodiments may attach the magnet to the end cap using a flexible tether such that the magnet is located externally to the handle. An example of such an embodiment is illustrated in FIG. 9. As is shown, a magnet 218 may be enclosed by or otherwise affixed to a pendant 902. The pendant 902 may be secured to a handle 702 using a flexible tether 904. Such an embodiment may provide additional security against a handle being unintentionally detached from the ferrous surface to which it was originally attached.

In addition to the end portion 202 illustrated in FIG. 2a , other embodiments of the invention may utilize an end portion with decorative elements applied or molded into the end portion. Examples may include logos and other graphic images. In certain embodiments, the end portions may be formed to simulate items that are of interest to a user or to conform to a stylistic theme followed by other products offered by a seller of the jump rope handles. An example of such an embodiment is illustrated in FIG. 10 where an end portion simulates a safety pin pull ring 1002 of a hand grenade.

In certain embodiments of the invention, items may be inserted into the jump rope handle to add weight to the handle. Such embodiments may assist a user in achieving a higher level of fitness as the result of having to resist the action of the increased weight of the jump rope handles.

An advantage of the disclosed embodiments of the invention is the interchangeability of the various components of the jump rope handle and rope. When using an embodiment of the invention, a user may change the bearings, handles, any weights, the rope, or end portions to suit that user's individual tastes or exercise goals. Depending upon the configuration of the user's jump rope handle, changing of one or more of the components may be performed with minimal tools.
